The inventi'onrelates to machines for forming briquettes, or the like. f

j The principal objectof the invention is to Y 'provide' avmachuine in which coal dust or the 5 refuse of gas generators or theflike, that still contains some fuel valuei, may be readily compressed into briquettesof such a size and shapefas to fit'a' fireplace;

Another object of he Vinventionl is'to pro- '10 j vide a machine for forming briquetteswhich chine isV so constructed as to compress the damp refuse material or coal dustthat remains in a gas generator after the production of gas into semicylindrical briquettes.

` Another object of the invention is to pro- 5. vide a briquetteeforming machine which is highly useful. and simple ink construction. Convenienceof arrangement and comparative inexpense of manufacture are further objects which have beenborne in mind inthe produc- 59 tion and development of thepinvention.

' Other objects of the' invention, together kwiththeV foregoing, will be set forth inthe following description of the preferred em-y bodiment of means for practicing theasame,

* it which is illustratedin the drawing Vaccompanyingand formingpart ofthe specification. i It is to be understood that I vdo not limit myself to the embodiment disclosed` in Y lsaid Vdescription and the drawings, as I may adopt variations of my preferred form within `the scope of my invent-ion, as set .forth lin the claims.` 1

A wheel 2 is rotatablymounted on the frame by` means of an axle `Flanges 4 are secured j tothe oppositesides'of the wheel2 by means "55 f l Of bolts 5 andnuts'. n The` flanges extend b'eyond the periphery o f the wheel '2, as it is clearly shown in Figurrev2, and form a channel 4 for the purpose tobehe'reinafter described. It istobe noted that the width of v60 the channel 4, formed 'by the flanges 4, may.

fbe adjusted to a certain extent'by the loosening or tightening up of the bolts and theV ,nuts 6. A second'wheel 7 i's secured on an axle 9, said axle being eccentrically and rotat-v .65 ably mounted invbearings 8 whichbearings, in turn, are adapted to be rotatedfinth'e frame'l, v l

- The first wheel 2and the second wheel 7 are in axial alignment when assembled. ySemi- 70 ycylindrical Agrooves Yl0 are provided on the outside periphery ofthe wheel 7.V The semi cylindrical grooves l0 extend transverselyon the periphery of said wheel andare disposed,

distance between the axle 3 andthe axle 19 is sofdetermined that the wheel 7 `is supported in such a relationl that the semi-cylindrical gIOoves 10 thereon extend intothe channel 1rv 4 on the Wheel 2. The wheels are rotated .bytel any'conventional means, and the power is transmitted to a gearlland agear 12 which, in iturn, rotate gearslgA vand* 14 securedrespectively to the axles 9 and .3. Itis tobe noted that the wheels 2 and 7 are rotated in op- -posite directions as it is indicatedJ by the- V"elr-ovs in Figure 1.A rlhe coal dust, or similar (material, is fed into a hopper 15 supported on the frame'Y l, and it is discharged :therefrom into the channel4 between the flanges 4. After the coal is discharged on the periphery of the wheel 2, itis carried thereby 1n the direction of the arrow toward the wheel 7.

The wheel 7 is rotated in a counter-clockwise I direction, and Vthe transverse Vcylindrical grooves l'the'reongradually approach the periphery of the wheel 2, thereby gradually pressing the coalodust or, liker material'into the semi-cylindrical shape as shown in Figure 3. The 'further rotating of thev wheels 2 and A7 results in the discharging of the briquettes 16 upon a conveyor, not shown, which may be disposed below the wheels 2 and 7 so as to carry the briquettes 16 to any point desired. In order to prevent the coal dust or similar substance falling out of the channel l over the flanges 4, while it is carried Vtoward the horizontal axis of the wheel, a plate 17'is provided. Said plate 17 is pivotally supported in a bracket 18 which, in turn, is pivoted to the frame 1. Theplate 17 is arcuate in shape and covers a portion of the channel, thereby slightly compressing the lcoal dust before it reaches the semi-cylindrical transverse grooves 10. The pressure exerted by the arcuate-shaped plate 17 on the coal dust may be readily adjusted by a setscrew 19 extend.- ing thru a lug 20, being integral with. the bracket- 18. It is evident that the turning of the set screw 19 readily regulates the position and the' pressure of the arcuate plate 17 upon and relative to the substance in the cha-nnel 4. i y l A scraper 21 is secured to the frame 1 so as to assume a tangential position relative to the periphery of the wheel 2 in order to scrape lall the coal dust or other material that may adhere thereto.

In order to prevent the pressing of any clinker or other rocky or hard substance into the briquettes and to obviate any danger of damage to the machinery by such hard rocks or clinkers mixed with the coal dust, I .pro- Vvide a safety mechanism for automatically changing the distance between the center of the wheels so as topermit `the elimination of the hard rocks or clinkers or large masses l of hard material from between the wheels.

4 anpporting member 24 and A bar 22 is pivctally secured at one end to the axle 9 of the wheel 7. The other end thereof is pivotally secured to Va link 23 which, in turn, is'pivctally secured to a supporting member 2a. VA coil spring 25 surrounds the the link 23 and it tends to maintain the same in a relatively perpendicular or upright position, thereby maintaining the axle 9 in aposition above the center `of ythe bearing 8 and the vertical center line thereof as shown in Figure 1. vWhen any clinker or rock tends Vto clog the machinery by being forced betweenV the wheel 2 and the wheel 7, the wheel 7 and the axle 9 are forced to swing outwardly away from I the wheel `2. i The bearing 8 is caused to turn in the frame 1, bythe eccentric movement Vof the axle 9, whereby the rod 22 is advanced Quidly and swings vthe link 23 against the. action of the coil spring 2 5. rlhus, sufficient clearance is provided between the wheels to permit the release ofthe clinker or rock therefrom. After the obstruction is removed. the action of the coil spring 25 returns the link 23, the 22, and the axle 9 'te' their `@femenil iwstienathersbr maintain ingthe wheels 2 and 7 in the operative position heretofore described. A

It will be recognized that a particularly simple device is provided to accomplish the forming of briquettes from the inferior inaterials which otherwise would go to waste; and that this machine combines ready adjustment and anv automatic' action with a ruggedness of construction and readiness of operation, especially adapting it forits use. Being a unitary character, the device requires no careful setting up and lends itself 'to effective application by the labor ordinarily available.
